Bones Swiss Precision Bearings are simply the best. Professionals and intermediates alike swear by these bearings and why? These bearings are strong, fast, smooth and durable - everything you could ever ask from a bearing. The hardened steel balls make them roll faster, stronger and are one of the lightest bearings on the market. They are also easy to clean. Each seal fits into a groove cut into the inner race without touching the walls or bottom of the groove, so that dirt and water must go through a Labyrinth or U shaped path to get to the inside of the bearing. The Bones Bearing team of skaters who have tried these note that they are just as fast as ever, but are quieter, and stay clean longer. Bones Bearing factory testing confirms this. Made of hardened steel balls with a removable high speed ball cage, removable non-contact frictionless rubber shields and lubricated with low viscosity Bones speed cream.

Q: I will be purchasing the new K2 Radical X Boa inline skates 2014 soon. I will be changing out the stock wheels of K2 s to roller blade hydrogen 110 and 100 85A for longer lasting outdoor usage. I'm also considering swapping out the ILQ 9 pro stock bearings to the Bones Swiss ceramic bearings that come in 7 or 8 mm. My question is what size of bearing will be compatible for my skate choice in K2 but using hydrogen wheels 85 A and Bones swiss 7 or 8 mm. Thank you for the support. Jeff

A: The Bones Ceramic Labyrinth bearings will work with the Ricta wheels. However the axle size will be the issue, as skateboard axles vary in diameter and may not be able to accommodate either size of bearing. I would recommend discovering your axle size before ordering a set of these bearings.
